PEORIA — Former Charter Oak Primary School Principal John Wetterauer may not be moving to Woodruff Career and Technical Center after all.

Wetterauer, a key subject in Peoria School District 150's investigation of testing irregularities involving how standardized tests were administered to special education students, was scheduled to report Monday to Woodruff as principal "on special assignment." He and Woodruff Principal Tom Blumer were to discuss what his new assignment entailed.

But Friday afternoon, Wetterauer asked to be placed on leave for the rest of the school year, apparently after District 150 spokesman Chris Coplan already had reported his reassignment to Woodruff. Wetterauer did not report to Woodruff on Monday, according to Coplan.

It was not clear if Wetterauer requested paid leave or when or how the board would handle his request. Coplan said the board would consider Wetterauer's request at a future meeting.

Wetterauer has not replied to calls for comment. His only response to the district's investigation has been through his attorney, Nile Williamson, who was not available Monday.

Wetterauer had been on paid administrative leave since December. The district's investigation alleged he failed to train teachers in how to properly administer the tests. After a series of board meetings packed with Wetterauer supporters pleading for his reinstatement, board members unanimously approved placing Wetterauer on special assignment at a different school and disciplining four Charter Oak special education teachers.

Two of the teachers — Deborah Lowe and Joan Schifeling — were given transfers and remedial warnings. The other two teachers, who were not named, will remain at Charter Oak.

The district sent its preliminary investigation to the Illinois State Board of Education, which could rule on suppressing test scores for the 26 students in question and, potentially, further discipline for the educators.
